Introduction

Design an instrument to determine power available vs. power required for low cost helicopters Requirements:

• Continuous atmospheric pressure and air temperature measurements
• Altitude calculation
• Power margin calculation (ceiling IGE, ceiling OGE)
• Data storage (downloadable)
• Indicator: LED or LCD
• Accurate and repeatable function
• Low cost and lightweight
• Portable (self-powered)
• Protection

Schweizer S-300C

Technical Terms

• Ceiling IGE In Ground Effect - increase in lift force generated from aircraft being

close to the ground

• Ceiling OGE Out of Ground Effect - decrease in lift force from aircraft being far

from ground

• Power Margins

Specifications

Operating range Battery life: 1 hour (for testing); 1/3 - 9 hours (for flight) Altitude: Sea level to 10,000 ft (for flight); testing at 2,000 ft Temperature: 30 °F to 150 °F Weather: Dry weather, non-icing

Specifications

Hardware Power Consumption: As little as possible Accuracy: As accurate as possible Size: As small as possible, should be portable Cost: Ideally < $300 Software Interface with a computer through a SD card (only SD card drivers required) (non end-user) Data organization can be done through MATLAB (non end-user) ATMEL Studio 6.1 will be used for programming (non end-user)

*Not to Scale

Budget

• Sikorsky will be providing us a $4,000 budget
• Our final projected cost is under $300 per unit
• Our prototyping cost breakdown:
• Weather Balloon:

$40

• Development/Debugger board:

$30

• Breadboard/wires:

$20 Total: $90

• Multiple prototypes will be built for testing

Design Decisions

Prototype: + Accurate Pressure Sensor + Data log System + Microcontroller + Battery Powered Final:

• Data Log System

+ Add More Sensors + Simple Feedback Display ■ Battery Powered

Design

I2C GPIO SPI

Optional Requirements

• Accept pilot input parameters
• Wind direction and speed measurements
• Humidity measurement
• Output numerical values for hover altitude, angle of climb
